ab8500_btem...ctrl_voltage(9)

✨ ab8500_btemp_read_batctrl_voltage — the page formally known as ab8500_btem...ctrl_voltage(9)

Hiii bestie 🫶 so this whole thing lives in the Kernel API Manual, and the title up top is that long squished little nickname ab8500_btem...ctrl_voltage(9) — but the actual function name is the full one in a sec. Don't let the abbreviation jump you, it's the same page, iykyk 💅

🌸 NAME 🌸

ab8500_btemp_read_batctrl_voltage — literally just: measure the batctrl voltage 🔋✨

🦋 SYNOPSIS 🦋

int ab8500_btemp_read_batctrl_voltage (struct ab8500_btemp *di );

That's it. That's the whole entire function signature. Short king 👑.

🎀 ARGUMENTS 🎀

• di — pointer to the ab8500_btemp structure 💖. Yeah. That's the entire description. She's a pointer to the ab8500_btemp struct, no further notes, no secret lore ngl.

⭐ DESCRIPTION ⭐

Okay so the vibe here is so simple it's giving main-character-with-nothing-to-prove: this function returns the voltage on BATCTRL 🌈.

And the return value? That's in mV — millivolts, bestie, write it down 😭. mv would be a whole different thing, this is millivolts.

no cap, that's genuinely the whole description. one job. ate and left absolutely no crumbs 🍓
